7D for youth hockey?

Is anyone using the 7D at this time for youth hockey? I'm currently using a 20D with a 70-200 2.8 and I'm ready to upgrade. Can I shoot 3200 iso without much noise? The rinks up here in the PNW are dark and poorly lit. Last game it seemed that every lamp was a different color and there were too few of them. Will the 7D increase the keeper rate under these conditions?

thanks

I am a beginner - i had purchased a 20d used over the summer and couldn't get any useful hockey pictures at f/4 so i purchased a 7d. I find for hockey and other sports the af is getting me more keepers and i am relatively happy with 3200 iso and the high fps. hoping to get a 2.8 next year. I would imagine the 7d and your 2.8 would be a killer combo. post some of your pictures...

this is 3200 iso, f/4, 1/500th through the glass
didn't do much post on this - still learning - i think it needs sharpening

I shot one game (well more of a scrimmage since no officials and no goalies) with my 7D last week.
I had shot hockey with other cameras before, mostly recently with the 5DII.
The arena here is dark. My preferred exposure is iso 6400 f4 1/500th, sometimes iso 3200 f2.8 1/500.
I set white balance with an expodisc. It helps although the lights cycle anyway so some shots look to be coloured differently. Still I think the expodisc is the best solution as the brightest shots tend to come out ok and setting WB off the ice has not worked that well for me.
I shot JPGs with standard NR set in the camera.
I was pleasantly surprised with the 7D at the hockey game.
I posted a lot of pictures from the "game" at

Almost all shot from the one elevated position (above the tinted glass) in one corner of the arena.
Used 70-200 f2.8 lens (IS disabled). Sometimes I wish I had a zoom that was longer, the 300mm f2.8 is not very flexible and very heavy to hold for long. Ideally would bring a second camera with a wider lens too, especially for shots from behind the goals.
Did not really notice any focus issues, the 8 fps is great to have.
